This park was constructed as a commemorative facility in accordance with the Hiroshima Peace Memorial City Construction Law promulgated in August 1948, under the project to make the whole neighborhood of the Nakajima district into a symbol of ever-lasting peace and a recreation area for citizens. Subsequently, the park was renovated into its current design in preparation of the 50th anniversary of the A-bombing.
The park, including the A-bomb Dome area, occupies an area of 122,100 m2. In February 2007, this park was designated as a place of scenic beauty in Japan for the first time among the parks renovated after World War II.
The Hiroshima Peace Memorial Ceremony is held in this park on August 6 every year.
